I checked the voltage at the fuel lockoff solenoid and got 9.6 VDC. A screwdriver stuck to the body of this solenoid while cranking. I have yet to check for voltage at the idle bypass solenoid. I believe this truck DOES have the trim injector on the carb. Down low, behind the carb (towards the firewall) there is one single electrical connector with one purple and one gray wire. The thing that this electrical connector goes to has a hose coming off it that goes to another unit which has a hose going to the fuel regulator.

Wow BREWSKI, you sure seem to know your lift trucks! Thanks for your help.
